s This invention relates broadly to apparatus for heading sheet metalcontainers,- and it has ,for its primary objectto' provide a mechanismfor effecting the heading of sheet 5. metalbarrels, drums and likecontainers in an eflicient and expeditious manner and withoutcrushing ordeforming any part of the container. d 7 A further ob ect is to provide,in associa- 10 tion with mechanism for seaming heads on 7 barrel bodies,means for rigidly supporting the head ends of. such bodies during theseaming of heads thereon. l f

' With these and other objects in view, the

2 l inventionfresidesjinthe features of construction, arrangement ofparts and combinations of elements which will hereinafter be fullydescribed, reference being had to'the accompanying drawings, in which+ 0i Figure 1 is aside-elevation'of theinvention, parts thereof being shownbroken;

, Figure 2 is a top planview of the mechanism for supporting the headend of the container during the heading operation;

Figure 3 is a detail section of the head end of a container with thehead loosely mounted therein, illustrating the application of the meansfor supporting said endduring the head attaching operation and Figure 4is a similar view showing the parts as they appear at the conclusion-ofthe head attaching operation.

Referring to said drawings, 1 designates a stationary upright columnupon which is rigidly carried a supporting frame oryoke 2 embodyingsubstantially parallel horizontally directed arm-like members 3 and 4having on their respective ends sleeve-bearings 5 and 6 disposed inverticallyalined relation.

Said bearings havejournaled for rotation therein a vertical spindle uponthe lower end of which is mounted a chuck 8 which carries on its underside a plurality of seam- V ing rollers 9. In order to provide forvertical' reciprocation ,of'said chuck8'relative to the worlqsaid's'pindlei7 is made longitudinally; shiftable in its saidbearings.

' Fixed on the spindle in'suitable locations between the bearings 5 and-6 are two relatively' spaced collars 10 and 11, and interposed inembracing relation to said spindle between said collars is a shifterring12 ha'vingsaid spindle rotatable relative thereto. Said shifter ringhas pivotally attached to diametrically opposite sides thereof the u perends of two parallel links 13 which ave their lower ends'rigidly mountedon the opposite ends of a transversely disposed horizontal shaft 14which is mounted for rotary movement in or on the lower member or arm 24 of the yoke 2. "Said links 13, which normally function to support thespindle 7 and the thereby-carried chuck 8 in elevated position, arejointed intermediate their ends, I

each being formed of two pivotally connected members which normallyoccupy alined relation. The joint 15 of each link is of knuckle type,permitting breaking, or'relative angular movement, of said link membersin a forward direction only from their relatively alined positions, suchbreaking being intended to permit said spindle to drop for lowering thechuck-upon the work. A- retractile coil spring 16 connected at one endto one of the members of each link adjacent to said joint 15 and at itsopposite end to a fixed part, as to a bracket 17 stationarily mounted atan appropriately elevated point on the yoke, nor mally maintains themembers of each link in their alined relation.

A hand lever 18 fixed on one end of the shaft lt is provided whereby thelatter may berotated forwardly to effect the breaking of the joints 15of the links as required to permit the spindle and the chuck to descendfor disposing the seaming rollers 9 in operative relation to the work.

The spindle 7 is rotated in any suitable manner, as through gearingconnecting it with an appropriately located power transmission shaft. Asherein showmsaid transmission shaft carries a bevelgear 20 in driv ingrelation to asimilar gear 21 fixed on a vertical shaft 22 journaled inbearings, as

23 and 2 1, thelatter formedon the yoke 2. A bevel gear 25'fixed' on theupper end portion of said shaft 22 is disposed in driving relation to asimilar gear 26 fixed on one end of a horizontal shaft 27 j ournale'd inbearings 28 mounted onthe arm 3 of the yoke. The opor 2 v posite end ofsaid shaft 27 carries a bevel gear 29 occupying driving relation to asimilar gear 30 Whichrests upon the top of said arm 3 and which issplined on the spindle and rel-V ative to which the latter isverticallyshiftable.

Vertically adjustable relative to the yoke 2, as along the column 1 andthe upright shaft 22,,is a supporting member 31 having a for-Wardlyprojecting arm Said 'ieinber is I supported by and isadjustedvertically by means of a screw 33. Said screw, which has itsupper endswiveled at -34 on the underside of the yoke 2, has threaded engagementwith said member 31. Thus, adjustment to position said member. at agreater orless elevation is effected by rotating said screw in therequired direction.

The arm 32 of the. supporting member 31 constitutes a mountm upon whichis rigidly carriedone member or section 35 of a horizontally disposedtwo-section clamping rlng des gned to embracea sheet-metal'drum body vduring the operation of seaming a head thereon by means of the rollers9;of the chuck 8. Saidring section35, which is substantiallysemi-circular in form, is further supported by appropriately locatedlegs 36, and pivotally attached to one end of said section is an end ofa complemental section 3'? which is supported by one, or morelegs 38havingrollers .orcasters 39 for travel on the floor during opening andclosing movements of said section relativeto the'stationary section35.

The opposite ends of said clamping ring sections 35 and 37 are providedwith means whereby they may temporarily be rigidly connected forrigidlyholding within their embrace the bodies ofdrums 40 during the operat1onofseammg heads thereon. r Said means,

as herein shown, comprises a projecting hook v 41 rigidly carried by theend of'the section 37 and a part 42 interengageable therewith, said part42 being borne a lever-like handle 43 which is pivotally mounted on thecorresponding end ofithe ringsection 35.- Said handle is adaptedto beswung manually to and from a position wherein the part 42 interengagesthe hook 41'for holding said ring sections infiXed relation, maintainingthe embraced drum body in stationary posltion d1- rectly under and in iI tered relation to the chuck 8.

'A handle 44 fixed on the ring section 37 in a suitable position servesas means whereby said section may be swung to andfroin its open positionwith respect to the stationary section 35' for;.permitting introductionand V removal of drums relative to-said sections.

Said clamping ring is designed toseat Within an annular channel/45formed exteriorl-y'of the drum bythe'provision in the latter of aninternal annular head 46. The

' upper surface'of said bead constitutes a seating ledge or shoulder forthe head .47 which )roperly a'lined or cendistorting or metal-buckl ingstrains which would otherwise be imposed thereon.

" The upper face ofthe clamping ring has formed therein adjacent. to itsinner edge a shallowv channel 51, arcuate in cross section, into which,in the heading operation, the metal ofthe seating ledge or shoulder isforced andwith the curvature of which said 7 ledge is caused. to

What is claimed is I I 71.v In drum heading apparatus, the combinationwith a chuck carryingseaming rollers, and means forshifting said chuckto carry said rollers into and out o-foperative seaming relation to theend of a drum body and a head mounted on; the latter, of a sectionalconform, as shown in ring for embracingsaid drum body in underi lyingsupporting relation toan offset shoulder formed in its said end,andmeansrigidly supporting said ring, said ring being adaptedto relieve the bodybelow said shoulder of r0ller-imposed pressure strains and having in itstop face a channel into which said shoulder is depressible.
